Abstract
The utility model discloses a mini-sized loudspeaker comprising a magnetic circuit system provided with a double-magnetic circuit structure. The magnetic circuit system comprises a magnetic-conductive basin rack, an inner magnet disposed on a center of the basin rack, and an outer magnet disposed on an edge position. The outer magnet adopts a rectangular strip-shaped structure. The outer magnet is provided with a foolproof structure, which is used for identification of the outer magnet installation direction, and is formed by outward processing. The mini-sized loudspeaker is advantageous in that the outer magnet is provided with a foolproof structure, which is formed by outward processing, andtherefore the installation direction of the outer magnet can be identified, and the product yield can be improved.

Technical field
The utility model relates to the electroacoustic field, is specifically related to a kind of Microspeaker.
Background technology
Microspeaker comprises magnetic circuit system, because thereby two magnetic route structure can obtain bigger power output and be widely used, a kind of two magnetic route structure that often adopts in the prior art comprises the internal magnet that is positioned at the center and is positioned at the external magnet of the strip of marginal position, usually the external magnet of using is the list structure of rectangle, and the thickness of external magnet is close with width.Owing to need magnetize according to specific direction in the external magnet manufacturing process, be difficult to distinguish the direction of width and thickness when installing for the external magnet of said structure, thereby cause external magnet installation direction mistake easily and cause product bad.Therefore, be necessary the Microspeaker of said structure is improved, to avoid above-mentioned defective.
The utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of Microspeaker, can distinguish the installation direction of external magnet, improves the rate of finished products of product.
To achieve these goals, the utility model provides a kind of Microspeaker, comprises the magnetic circuit system of two magnetic route structure, and described magnetic circuit system comprises the basin frame of magnetic conduction, and the internal magnet and the external magnet that is installed on marginal position that are installed on described basin frame center; Described external magnet is the list structure of rectangle, and wherein, described external magnet is provided with the error-proof structure of expecting the described external magnet installation direction of the identification that forms.
In addition, preferred scheme is, described error-proof structure is to expect the rounding structure that forms.
In addition, preferred scheme is, described error-proof structure is to expect the bevelling structure that forms.
In addition, preferred scheme is, described error-proof structure is to expect the stair-stepping structure that forms.
In addition, preferably scheme is, described magnetic circuit system forms magnetic gap, and described error-proof structure is arranged at described external magnet near a side of described magnetic gap.
In addition, preferably scheme is, the side that external magnet is installed on the described basin frame is provided with the limiting section of projection, and described limiting section is arranged at described external magnet near the bight of described internal magnet.
After adopting technique scheme, compare with traditional structure, the utility model is provided with at external magnet expects the error-proof structure that forms, thereby can identify the installation direction of external magnet, has improved the rate of finished products of product.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done further detailed description.
Embodiment one: as depicted in figs. 1 and 2, the magnetic circuit system of Microspeaker is the basin frame 2 that two magnetic route structure comprises magnetic conduction, the upper surface of basin frame 2 is combined with internal magnet 12 and external magnet 11, and wherein external magnet 11 is the list structure of rectangle, is arranged at two major axis avris of internal magnet 12.Internal magnet 12 and external magnet 11 be mode and basin frame 2 secure bond by bonding normally, and there is interactional attraction between external magnet 11 and the internal magnet 12, for fear of the effect owing to attraction external magnet 11 is moved to the direction of internal magnet 12, the utility model is provided with protruding limiting section 21 in the side that basin frame 2 is positioned at external magnet 11, limiting section 21 is connected to the bight of external magnet 11, thereby can avoid because the movement of the external magnet 11 that the interaction force between internal magnet 12 and the external magnet 11 causes.
In the magnetic circuit system, space between external magnet 11 and the internal magnet 12 forms the magnetic gap 13 of accommodating the voice coil loudspeaker voice coil (not shown), as shown in Figure 2, the utility model error-proof structure 111 is arranged at external magnet 11 near a side of 13 of magnetic gap, error-proof structure be arranged at this position can so that with the isostructural installation of Microspeaker shell, but be not limited to this structure.In the present embodiment, the error-proof structure 111 rounding structure for going to expect to form, as depicted in figs. 1 and 2, in the assembling process, only need error-proof structure 111 with rounding be arranged near a side of magnetic gap 13 and can avoid the product that causes owing to the installation direction mistake bad, thereby improved the rate of finished products of product.
Embodiment two: as shown in Figure 3 and Figure 4, the main distinction of present embodiment and embodiment one is, error-proof structure 111 ' the bevelling structure for going to expect to form, equally, present embodiment error-proof structure 111 ' is arranged at the side near magnetic gap, makes the error-proof structure 111 ' of external magnet 11 ' be arranged at magnetic gap one side during assembling and gets final product.This structure can be identified the installation direction of external magnet 11 ' equally, has improved the rate of finished products of product.
Embodiment three: as shown in Figure 5 and Figure 6, the main distinction of present embodiment and embodiment one is, error-proof structure 111 " bevelling structure for going to expect to form; present embodiment error-proof structure 111 " be arranged at the side near magnetic gap equally, make external magnet 11 during assembling " error-proof structure 111 " be arranged at magnetic gap one side and get final product.This structure can be identified external magnet 11 equally " installation direction, improved the rate of finished products of product.
Under above-mentioned instruction of the present utility model; those skilled in the art can be in his improvement of the basic enterprising Xingqi of above-described embodiment and distortion; and these improvement and distortion; all drop in the protection range of the present utility model; those skilled in the art should be understood that; above-mentioned specific descriptions are just better explained the purpose of this utility model, and protection range of the present utility model is limited by claim and equivalent thereof.
